[m-rev.] diff: more documentation updates

[Julien Fischer]

More documentation updates.

.README.in:
 	The contents of java/runtime come under the LGPL as well.

 	Minor rewording.

README.MS-Windows:
 	We don't need to list every version of Windows we no longer
 	actively support.  (If the version is not on the list of those
 	we *do* support, then we don't support it.)

README.MacOS:
 	We will never support compiling Mercury with llvm-gcc on
 	Mac OS X 10.5 and 10.6.

Julien.
